[0007] By adopting the above technical solution, the staff installs the cling film roll on the film supply device, the cling film passes through the film positioning plate, the film pressing assembly makes the cling film stick to the film positioning plate, and fills the skin material and filling material into the stuffing device. In actual work, the stuffing device wraps the skin material on the outside of the stuffing ball, and the formed green dumpling falls in the vertical direction, passes through the through hole on the film positioning plate, and falls into the presentation cup.

At the same time, the driving assembly drives multiple tightening knife blocks to rotate relative to each other, and the back of the previous tightening knife block and the blade of the next tightening knife block slide relative to each other, driving the annular opening to close. After the cling film is wrapped on the formed green dumpling from bottom to top, the upper sides fit each other, thereby completing the wrapping of the formed green dumpling. While the tightening knife block rotates, the film cutting device cuts the cling film.

[0043] The transmission device 9 can be configured as a conveyor belt, or a packaging box or a presentation box can be further configured on the conveyor belt. The front end of the conveyor belt is configured at the lower side of the rotating frame 41.

[0044] The implementation principle of the green dumpling forming and film-wrapping integrated machine of the present application embodiment is as follows: before starting the equipment, the staff puts the leather material into the leather material supply machine, puts the filling material into the filling material supply machine, installs the cling film roll on the positioning roller 22, passes one end of the cling film between the driving roller 241 and the pressing roller 28, and after winding it on multiple tensioning rollers 29, it is attached to the film positioning plate 5 on the lower side close to one side of the film supply device 2, and controls multiple driving cylinders 73 on the corresponding film positioning plate 5, so that the pressure strips 71 on both sides of the length direction of the film positioning plate 5 are pressed against both sides of the width direction of the cling film. Then, by adjusting the rotating handle 261, the pressing roller 28 is pressed against the cling film. The staff starts the Qingtuan forming and film wrapping integrated machine, and the film feeding motor 24 drives the driving roller 241 to rotate, and the driving roller 241 drives the plastic wrap forward. At the same time, the driving motor drives the rotating shaft 411 to rotate around its own axis, thereby driving the rotating frame 41 to rotate, and the plastic wrap is tightly wrapped and attached to the multiple film positioning plates 5 on the side close to the film supply device 2, and the multiple corresponding driving cylinders 73 are controlled, so that the multiple pressure strips 71 are pressed against the corresponding edges of the plastic wrap. At the same time, the skin material supply machine squeezes out the Qingtuan skin material, and the Qingtuan skin material falls into the stuffing knife disc 33, and the stuffing material supply machine squeezes out the stuffing, and the stuffing falls on the upper side of the Qingtuan skin material, and the stuffing knife disc 33 wraps the Qingtuan skin material around the outside of the stuffing to form a Qingtuan.

[0045] At this time, the driving motor drives the rotating frame 41 to rotate, so that the through hole 51 on the film positioning plate 5 with the plastic wrap film on the uppermost side corresponds to the stuffing knife disc 33. The cutting cylinder 81 drives the blade 82 to cut the plastic wrap film. The stuffing knife disc 33 loosens the formed green rice dumpling, and at the same time, the driving cylinder 73 drives the pressure strips 71 on both sides of the film positioning plate 5 to lift up, and the green rice dumpling falls on the plastic wrap film, and then passes through the through hole 51 and falls into the presentation cup 53. The flexible clamp 531 grabs the lower side of the green rice dumpling wrapped with plastic wrap, and the piston rod of the rotating cylinder 64 is extended and retracted, driving the driving disc 63 to rotate relatively, thereby driving the annular opening to tighten, so that the opening of the plastic wrap film on the upper side of the green rice dumpling is tightened. At the same time, the rotating motor 54 drives the presentation cup 53 to rotate and tighten the plastic wrap film. The rotating cylinder 64 drives the driving disk 63 to reverse, driving the annular opening to open, and at the same time the driving motor drives the rotating frame 41 to rotate, and the next film positioning plate 5 moves to the position corresponding to the stuffing knife disk 33, and the above operation is repeated to continuously film multiple green rice dumplings. When the film positioning plate 5 with the film-wrapped green rice dumplings moves to a position close to the feeding end of the transmission device 9, the flexible clamping claw 531 releases the green rice dumplings, and the film-wrapped green rice dumplings are affected by gravity, pass through the through hole 51, and fall on the feeding end of the transmission device 9, and then are transmitted out of the green rice dumpling forming and film-wrapping integrated machine.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
